After hundreds of years of changes, the car lights have developed from the original incandescent lamp to the current offroad LED light bar. You may be familiar with halogen bulbs and xenon bulbs. Currently, the car lights have developed into offroad LED light bar.

What is the difference between offroad LED light bar and halogen bulb?
Offroad LED light bar is a rising technology in recent years. Although its price is not cheap, it is more advanced than halogen bulbs. In addition to being beautiful, long service life is also a major advantage of offroad LED light bar. Generally, the service life of offroad LED light bar is about 100000 hours, while that of traditional halogen lamp is only about 3000 hours. The plasticity of offroad LED light bar is also quite good.
The light source we use most in our daily life is incandescent lamp. But it has short service life. People inject halogen gas into the bulb. The tungsten atoms evaporated from the filament meet with iodine atoms at high temperature to produce tungsten iodide compound. When the tungsten iodide compound contacts the incandescent filament, it will decompose and reduce to tungsten and iodine. Tungsten will return to the filament and Iodine re-enters the gas and circulates so that the filament will hardly burn out and the bulb will not blacken. It is simple, cheap, easy to adjust the brightness and has a good color rendering.
What is the difference between offroad LED light bar and xenon bulb?
Offroad LED light bar is light-emitting diode, which is an electronic light-emitting device. Solid semiconductor chips are used as light-emitting materials to emit light directly through photon emission caused by carrier recombination. Now most headlights used in cars are LED light sources due to its cheap price, durability, compact structure, long lifespan and fast response.
Xenon bulb means a high-pressure gas discharge heavy metal lamp, filling a variety of chemical gases such as xenon and other inert gases in the anti-ultraviolet crystal quartz glass tube. It increases the triggered voltage through the supercharger to instantly increase the on-board 12-volt power supply to 23000 volts to protect the automotive power supply. It stabilizes the lighting of the lamp and improves the efficiency of use. Xenon bulb has more than twice the lighting effect of halogen bulb with better safety. It will not go out in an instant once the xenon lamp fails. Xenon headlights do not produce excess glare and do not interfere with oncoming drivers. However, the penetration rate is low in rainy, snowy and foggy days. It flames out automatically because of electromagnetic interference due to excessive starting current.
What are the roles of offroad LED light bar?
The light of the low beam is weak and the irradiation range is only close to the front of the vehicle. This kind of offroad LED light bar is mostly inclined to the ground in front of the vehicle, which has little impact on others. However, in rainy and foggy weather with low visibility, the lighting effect will be very limited
The side marker offroad LED light bar is mainly used to display the general outline of the vehicle. It is mostly used in rainy and foggy weather or weak lighting at night. If the vehicle breaks down, you can also turn on the wide light to remind others.
In rainy and snowy weather, heavy fog or at night with low visibility, ordinary lighting cannot effectively penetrate the rain and dense fog. The fog offroad LED light bar has strong penetration, which can play the role of lighting and warning in extreme weathers. However, under the condition of sufficient light, turning on the fog lamp will cause interference to others’ line of sight.
Foshan Nanhai Ginto Lighting Electrical Co., Ltd puts a lot of emphasis on relentless dedication to innovation and development to LED lights which helps our overseas customer stand outstanding in their markets and surpasses all the most respected players in the industry.
